本文实例讲述了python3实现的简单工资管理系统。分享给大家供大家参考，具体如下：

工资管理系统要求：

1. 查询员工工资

2. 修改员工工资

3. 增加新员工记录

4. 退出

执行代码：

#!/usr/bin/env python3

# author:robert

# --*-- coding: utf-8 --*--

def file_test():

with open("info.txt",'r',encoding="utf-8") as f:

file = list(f)

return file

def server():

for i in range(1):

print("1.查询员工工资\n2.修改员工工资\n3.增加新员工记录\n4.退出")

return i

loginsucces = false

while true:

i = server()

serial_number = input("请选择你的服务>>:")

if serial_number.isdigit():

serial_number = int(serial_number)

file = file_test()

if serial_number < 5 and serial_number >= 0:

if serial_number == 1:

name = input("请输入要查询的员工姓名:").strip()

for i in file:

file = i.strip().split()

if name in file:

break

for i in file:

if name in file:

name_sum = file[1]

print("\033[32;1m%s的工资是：%s\033[0m\n"%(name,name_sum))

break

else:

print("\033[31;1m没有此用户！\033[0m\n")

elif serial_number == 2:

name_old = input("请输入要修改的员工姓:").strip()

for ii in file:

file = ii.strip().split()

if name_old in file:

print(file)

sum_old = file[1]

name_alter,sum_alter = input("请输入修改的新员工姓名和工资，用空格分割:").strip().split()

with open("info.txt","r",encoding="utf-8") as f:

lines = f.readlines()

with open("info.txt","w",encoding="utf-8") as f_a:

for line in lines:

if name_old in line:

line = line.replace(name_old,name_alter)

f_a.write(line)

f_a.close()

with open("info.txt", "r", encoding="utf-8") as f:

lines = f.readlines()

with open("info.txt", "w", encoding="utf-8") as f_b:

for line in lines:

if name_alter in line:

line = line.replace(sum_old,sum_alter)

f_b.write(line)

f_b.close()

print("修改成功")

break

if loginsucces == true: break

else:

print("\033[31;1m没有此用户！\033[0m\n")

elif serial_number == 3:

try:

name_new, sum_new = input("请输入要增加的员工姓名和工资，用空格分割:").strip().split()

except valueerror:

print("\033[31;1m输入的参数不够！\033[0m\n")

else:

if name_new.isalpha() and sum_new.isdigit():

for ii in file:

file = ii.strip().split()

if name_new not in file:

with open("info.txt", "a+", encoding="utf-8") as f_c:

f_c.write("\n%s %s"%(name_new,sum_new))

print("增加成功")

break

if loginsucces == true: break

else:

print("\033[31;1m参数类型不对！\033[0m\n")

elif serial_number == 4:

print("\033[31;1m谢谢使用，下次再见！\033[0m\n")

exit()

else:

print("\033[31;1m请输入正确的序号！\033[0m\n")

else:

print("\033[31;1m输入的不是整数！\033[0m\n")
